FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
500 AM AST MON FEB 2 2026
DISCUSSION
A FRONTAL BOUNDARY ACROSS THE REGION WILL SUPPORT A WET PATTERN
TODAY. THROUGH LATE TUESDAY NIGHT, WINDS WILL INCREASE BETWEEN 20
AND 25 KNOTS AND FROM THE NORTH TO NORTHEAST. THIS WILL CAUSE
BREEZY CONDITIONS ACROSS THE ISLANDS, AND IN COMBINATION WITH
ABUNDANT MOISTURE CONTENT WILL PROMOTE AN ADVECTIVE WEATHER
PATTERN WITH SHOWERS INCREASING IN FREQUENCY AND INTENSITY OVER
THE LOCAL WATERS AND ACROSS ALL THE ISLANDS. THE FIRE WEATHER RISK
SHOULD REMAIN LOW TODAY.
